Application fled member 4, 1922. Serial no. 604,707.

My present invention relates to electrodes for electron discharge devices and more particularly to electrodes adapted tobe employed in devices in which current conduc- 6 tion is effected principally by means of an electron flow across an evacuated space.

The object of my invention is to provide a stron and rigid .electrode construction which will be simple in its manufacture and adapted for convenient mounting in the device in which it is to be emplo ed.-

The novel features which I elieve to be characteristic of my invention are set forth with particularity in the appended claims.

v understood by reference to the following description taken in connection with the accompanying drawing in which F ig.f1 is an elevation of an electrode constructed'in accordance with my invention showing the mannerin which the electrode may be supported; Fi 2 is an enlarged elevation of the electro e itself; Fig. 3 is an exploded plan view of the electrode; and Fig. 4 is a plan view of a portion of the electrode indicating the manner in which the parts of.

the electrode are fastened together.

In the drawing I have shown an electrode which is suitable for use as an anode in devices of the well-known kenotron and pliotron type.' This electrode is made up of two similar members of sheet metal 1 and 2 each of'which has parallel edge portions 3 and 4, and' an edge portion 5, which is adapted to be bent over the adjacent edge portion of the other member to clamp the two ortions together, as indicated n Fig; 4. Ilhch member. also has an offset portion 6 intermediate the edge portions, and these offset portions lie in parallel planes when the electrode is assembled and enclose a space in which another electrode orelectrodes may be located.

The electrode described may be sup orted on two arms7 which are embraced 'y-the edge portions 3 and 4 of members 1 and 2, whereby the electrode is secured to these arms when the two members are clamped together. The arms 7 may be secured to a clamping band 8 adapted to surround the glass stem'9 through which the leading-1n conductors for supp yin'gcurrent to the electrodes of the completed device are sealed.

As an additional means for holding the .two members together holes 10 may be My invention itself, however, will best be punched through the two members and the punched out metal around the ed e of the oles hammered down as indica in Fig.1 2. Kinks 11 may also be formed in the supporting arms 7 to the electrode sliding downwardly on the arms 7.

While I have shown and described the preferred embodiment of my invention it will be apparent that many changes in the precise structure of the electrode may be prevent any possibility of NEW YORK, nssrenon are GENERAL ELEO- made without departing from the scope of my invention as set forth claims.

What I claim as new and desire to secure by Letters Patent of the United States, 1s,-- a

1. An electrode for an electron discharge device comprising two similar members of sheet metal each of which has two edge portlons lying in the same plane and an offset portion between said edge portions, one of the edge portions of each member being bent over an adjacent edge portion of the other member to clamp the two members together.

2. An electrode for an electron discharge devicecomprising two similar members of sheet metal each of which has two edge portions lying adjacent toand parallel to two edge portions of the other and each of which members has an ed e portion which is bent over the ad'acent cf other member to clamp the two members together.

3. An electrode for an electron discharge device comprising two similar members of sheet metal eachof which .has two. ed e portions lying in the same lane .and an o set portion between said e fie portions, one of the edgeportions of eac memberibeing bent overan adjacent edge portionbf the other member to clamp the two members together, and said ofi'set portions of said members lying in parallel planes and enclosing between them a space suitable for the location of cooperating electrodes.

4. An electrode for an electron discharge device comprising two similar'members of in the appended ge portion of the sheet metal each of which has two edge portions lying adja'centfto and parallel to two edge portions of the other and each,

of which members has an edge portion which termediate portion which is in a parallel plane to an intermediate portion of the other member.

5. An electrode for an electron discharge device comprising two similar members of sheet metal each of which has two edge portions lying adjacent to and arallel to two edge portions of the other an each of which members has an edge portion which is bent over the adjacent edge portion of the other member to clamp the two members together, each of said members having an intermediate portion parallel to an intermediate portion of the other member, said parallelintermediate portions enclosing between them a space suitable for the location of cooperating electrodes.

6. An electrode for an electron discharge device comprising two similar members of sheet metal each of which has two edge portions lying, in the same plane and an offset portion between said edge portions, one of the edge portions of each member being bent over an adjacentedge portion of the other member to clamp the two members together, and a supporting arm for said electrode which is embraced by adjacent edge portions of the two members;

7. An electrode for an electron discharge device comprising two similarmembers of sheet metal each of which has two edge portions lying adjacent toand parallel to two edge portions of the other and each of which members has an edge portion which is bent over the adjacent edge portion of the other member to clamp the two members together, and a supporting arm for said electrode which is embraced by adjacent edge portions of the two members.

8. An electrode for an electron discharge device comprising two similar members of sheet metal each of which has two edge portions lying adjacent to and parallel to two edge portions of the other and each of which members has an ed e portion vwhich is bent over the adjacent ed other member to clamp the two members together, each of said members having an intermediate portion parallel to an intermediate portion of the other member, said parallel intermediate portions enclosin between them a space suitable for the ocation of cooperating electrodes, and a supporting arm for said electrode which is embraced by adjacent edge portions of the two members.

In Witness whereof, I have hereunto set my hand this first day of December, 1922.
